  </Step>

  <Step title="Create an order by passing the `customer_id` and the method as `nac...">
    Create an order by passing the `customer_id` and the method as `nach`. Razorpay generates a NACH form with the customer information pre-filled and ready to sign.
  </Step>

  <Step title="The customer can get the form in one of the following ways to sign it:">
    The customer can get the form in one of the following ways to sign it:

    * You can download the form from the Dashboard and send it to the customer.
    * A customer can download the form from the Hosted page (in the case of registration links).
  </Step>

  <Step title="The signed form can be uploaded in one of the following ways:">
    The signed form can be uploaded in one of the following ways:

    * Using the Standard Checkout page.
    * Hosted page (in the case of registration links).
    * The customer can send you the form and you can upload the form for the customer. The acceptable image formats and size are:
    * jpeg
    * jpg
    * png
    * Maximum accepted size is 6 MB.
  </Step>
</Steps>

Once the details are validated, the authorisation transaction is completed and a token is generated. You can charge your customer as per your business model after the token status changes to `confirmed`.

The acceptable image formats and size are:

* jpeg
* jpg
* png
* Maximum accepted size is 6 MB.

## Ways to Accept Authorisation Payment

You can create an authorisation transaction using the [Razorpay APIs](#11-using-razorpay-apis) or [Registration Link](#12-using-a-registration-link).

## 1.1. Using Razorpay APIs

To create an authorisation transaction using the Razorpay APIs, you need to:

### 1.1.1. Create a Customer

Razorpay links recurring tokens to customers using a unique identifier generated through the Customer API.

You can create [customers](/api/customers) with basic information such as `email` and `contact` and use them for various Razorpay offerings. The following endpoint creates a customer.

/customers

### Sample Code

````cURL: Curl theme={null}
curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
-X POST https://api.razorpay.com/v1/customers \
-H "Content-Type: application/json" \
-d '{
  "name": "Gaurav Kumar",
  "email": "gaurav.kumar@example.com",
  "contact": "+919876543210",
  "fail_existing": "0",
  "notes":{
    "note_key_1": "September",
    "note_key_2": "Make it so."
  }
}'

```java: Java
RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

JSONObject customerRequest = new JSONObject();
customerRequest.put("name","Gaurav Kumar");
customerRequest.put("contact","+919876543210");
customerRequest.put("email","gaurav.kumar@example.com");
customerRequest.put("fail_existing", "0");
JSONObject notes = new JSONObject();
notes.put("notes_key_1","Tea, Earl Grey, Hot");
notes.put("notes_key_2","Tea, Earl Grey… decaf.");
customerRequest.put("notes",notes);

Customer customer = razorpay.customers.create(customerRequest);

```python: Python
import razorpay
client = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET"))

client.customer.create({
    'name': 'Gaurav Kumar',
    'email': 'gaurav.kumar@example.com',
    'contact': '+919876543210',
    'fail_existing': "0",
    'notes': {'note_key_1': 'September', 'note_key_2': 'Make it so.'}
    })

```go: Go
import ( razorpay "github.com/razorpay/razorpay-go" )

        "notes_key_2": "Tea, Earl Grey… decaf.",
    },
}
body, err := client.Customer.Create(data, nil)

```php: PHP
$api = new Api($key_id, $secret);

$api->customer->create(array('name' => 'Gaurav Kumar', 'email' => 'gaurav.kumar@example.com','contact'=>'+919876543210','fail_existing' => "0", 'notes'=> array('notes_key_1'=> 'Tea, Earl Grey, Hot','notes_key_2'=> 'Tea, Earl Grey… decaf'));
```csharp: .NET
RazorpayClient client = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

Dictionary options = new Dictionary();

options.Add("name", "Gaurav Kumar"); 
options.Add("contact", "+919876543210"); 
options.Add("email", "gaurav.kumar@example.com"); 
options.Add("fail_existing", "0"); 

Customer customer = Customer.Create(options);

```ruby: Ruby
require "razorpay"
Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET')

para_attr = {
  "name": "Gaurav Kumar",
  "contact": "+919876543210",
  "email": "gaurav.kumar@example.com",
  "fail_existing": "0",
  "notes": {
    "notes_key_1": "Tea, Earl Grey, Hot",
    "notes_key_2": "Tea, Earl Grey… decaf."
  }
}

Razorpay::Customer.create(para_attr)

```javascript: Node.js

### 1.1.2. Create an Order

Use the [Orders API](/api/orders) to create a unique Razorpay `order_id` that is associated with the authorisation transaction. The following endpoint creates an order.

/orders

````cURL: Curl theme={null}
curl -u : \
-X POST https://api.razorpay.com/v1/orders \

<Info>
  **Download and Upload the Pre-filled NACH Form**
</Info>

Once the order is created, the pre-filled form must be downloaded, signed by your customer and uploaded back to Razorpay to complete the transaction.

You receive the following parameters as part of the response:

`prefilled_form`
: The link from where you can download the pre-filled NACH form.

`upload_form_url`
: The link where the NACH form should be uploaded once it is signed by the customer.

**Authorisation transaction + auto-charge first payment**:

You can register a customer's mandate **and** charge them the first recurring payment as part of the same transaction. Refer to the [Paper NACH section under Registration and Charge First Payment Together](/api/payments/recurring-payments/paper-nach/auto-debit#1-create-an-authorization-transaction) for more information.

#### Request Parameters

`amount` *mandatory*
: `integer` Amount in currency subunits. For Paper NACH, the amount has to be `0`.

### 1.1.3. Create an Authorisation Payment

After you create an order, you have to create an authorisation payment. To create an authorisation payment:

1. Download the Paper NACH form and send it to the customers.
2. Ask the customers to fill the form and send it to you.
3. You upload the received form via the create NACH File API. The acceptable image formats and size are jpeg, jpg and png. Maximum accepted size is 6 MB.

Use the below endpoint to upload the signed Paper NACH form via APIs.

/payments/create/nach/file

Razorpay's OCR-enabled NACH engine submits the form to NPCI on successful verification and you will receive a success/failure response.

#### Error Reasons

To learn about errors, refer to the FAQ [Upload the NACH File](/payments/recurring-payments/paper-nach/faqs) section.

## 1.2. Using a Registration Link

Registration Links are an alternate way of creating an authorisation transaction. If you create a registration link, you need not create a customer or an order.

When you create a registration link, an [invoice](/payments/invoices) is automatically issued to the customer. The customer can use the invoice to make the Authorisation Payment.

Know how to [create Registration Links](/payments/recurring-payments/create) using the Dashboard.

<Info>
  **Handy Tips**
</Info>

You can use webhooks to get notifications about successful payments against a registration link. Know more about [Webhooks](/api/payments/recurring-payments/webhooks#check-authorization-link-status-using-webhooks).

In the case of Paper NACH, the order amount must be `0`.

### 1.2.1. Create a Registration Link

Use the below endpoint to create a registration link for recurring payments.

/subscription\_registration/auth\_links

<Info>
  **Download and Upload the Pre-filled NACH Form**
